LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18058397 titled 'LIGHT-EMITTING DEVICE AND ELECTRONIC APPARATUS INCLUDING THE SAME
Simplified Explanation
The abstract of this patent application describes a light-emitting device that consists of two emission layers. The first emission layer contains a first host, while the second emission layer contains a second host and a third host. The hole mobility of each host is denoted as μH and must satisfy certain expressions.
- The patent application describes a light-emitting device with multiple emission layers.
- The device includes a first emission layer with a first host and a second emission layer with a second host and a third host.
- The hole mobility of each host, denoted as μH, must meet specific conditions.
- The abstract does not provide further details on the specific structure or function of the device.
Potential Applications
- This technology could be applied in various lighting applications, such as LED displays, lighting fixtures, or backlighting for electronic devices.
- It may also find use in optoelectronic devices, such as organic light-emitting diodes (OLEDs) or organic photovoltaic cells.
Problems Solved
- The patent application does not explicitly mention any specific problems being solved by this technology.
- However, the use of multiple emission layers with different hosts may offer advantages in terms of color tuning, efficiency, or stability in light-emitting devices.
Benefits
- The use of multiple emission layers with different hosts can potentially enhance the performance and versatility of light-emitting devices.
- By controlling the hole mobility of each host, the device's efficiency, color accuracy, and stability may be improved.
- This technology may enable the development of more advanced and customizable lighting solutions.
Original Abstract Submitted
In a light-emitting device, an emission layer includes a first emission layer and a second emission layer, the first emission layer includes a first host, the second emission layer includes a second host and a third host, and a hole mobility of the first host (μH), a hole mobility of the second host (μH), and a hole mobility of the third host (μH) satisfy Expressions (1) and (2) below:
